Detergent and fabric care additive containing carboxylic acid polymer |
(57) The present invention provides a detergent and fabric care additive containing a
high molecular weight carboxylic acid polymer excellent in solubility in the use of
a fabric treatment product such as a detergent and fabric care additive. A detergent
and fabric care additive containing a carboxylic acid polymer powder, wherein the
carboxylic acid polymer powder satisfies the following conditions (a) and (b) [(a)
at least one of conditions that a 0.2% by weight aqueous solution has a viscosity
of 10 mPa.s or higher and that a 1% by weight aqueous solution has pH lower than 6
and a 10% by weight aqueous solution has a viscosity of 300 mPa.s or higher and (b)
at least one of conditions that 50% by weight or more of the carboxylic acid polymer
powder passes through 20 mesh of a sieve according to JIS (Z8801) and that the average
particle diameter is 600 µm or smaller]. A detergent and fabric care additive containing
a carboxylic acid polymer powder, wherein the carboxylic acid polymer powder satisfies
the following conditions (c) and (d) [(c) a 0.2% by weight aqueous solution of the
carboxylic acid polymer powder has a viscosity of 10 mPa.s or higher and (d) the carboxylic
acid polymer powder contains a carboxyl group and a sulfonic acid group and the ratio
of the sulfonic acid group-containingmonomer relative to 100% by mole of all monomers
comprising the polymer is not less than 0.5% by mole and not more than 90% by mole].
